Abstract

A high-speed memory (4) is constructed so that it is provided with at least a first data-storage region (4a) which is accessed by a processor (1) and a second data-storage region (4b) into which data in a low-speed memory (5) is transferred and stored. The processor (1) reads data out of the first data-storage region (4a) of the high-speed memory (4), then transfers the data in the second data-storage region (4b) of the high-speed memory (4) into the first data-storage region (4a), and also accesses the low-speed memory (5) to transfer data therein into the second data-storage region (4b) of the high-speed memory, so that the processor can continuously read out data regardless of any access to the low-speed memory.
